This product includes one heavy-duty steel insert for our AgTec PVC fence rails. Each insert is engineered to slide smoothly into the center channel of the vinyl rail, locking into place to provide long-term structural support.

By adding this steel reinforcement, your PVC rails gain exceptional resistance to warping, bending, sagging, or twisting and other common issues caused by heat, sun exposure, heavy impact, or long unsupported spans. The insert enhances overall rail rigidity, helps maintain straight lines along your fence, and extends the lifespan of your installation.

These inserts can be installed after warping has occured to help to re-straighten a warped rail. Especially important for black rails that are more susceptible to warping.
